Mariners manager Scott Servais agreed to terms Friday on a multiyear contract extension.
Servais, 51, is already the fourth-winningest manager in Mariners history at 222-199 (.527) midway through his third season. He was named as the 20th manager (17th full-time) in Mariners history on Oct. 23, 2015.
"Scott has created a culture here in Seattle that allows players to be successful," executive vice president and general manager of baseball operations Jerry Dipoto said. "They are encouraged to be themselves, which has resulted in a loose environment, while still maintaining the focus on team above self. His leadership has also been evident through the ongoing growth and impact of one of the best coaching staffs in Major League Baseball.
